This alloy centre differential housing is a replacement component for the HPI Bullet 3.0 Monster Truck and Stadium Truck centre gearbox. Supplied as a two piece set, the housings replace the factory centre shell and provide a firmer mounting location for the centre gears and bearings.
The alloy material gives better wear resistance than the original plastic shells and increases stiffness at the centre mounting points. That improved rigidity can help keep gear mesh consistent when the drivetrain is under load. Suitable for compatible 1/10 scale nitro MT and ST assemblies.
Installation involves standard disassembly of the centre gearbox, removal of the old housing, transferring bearings and internal gears, and secure reassembly using the original fasteners. Always check gear mesh and bearing seating after fitting, then perform a short test run to verify smooth operation.
Fit this alloy housing to reinforce the centre assembly and preserve consistent gear engagement during tuning and maintenance tasks.
